Question 634804
Unfortunately 2 hours isn't enough time (usually). The answer/response time varies on this site.



Let x = original dimensions


Since you're taking 1 ft from each side, you're taking 2*1 = 2 feet from each dimension.


So each dimension becomes x-2


So the volume is V = 1*(x-2)*(x-2)


which becomes


V = (x-2)^2



Since the volume is 16, we can say


(x-2)^2 = 16


Now solve for x


(x-2)^2 = 16


x-2 = sqrt(16)


x-2 = 4


x = 4+2


x = 6


So the original box was 6 feet by 6 feet.
